Nano-Composite Nylon6

Environmental Properties

• Water-Absorbing Speed

  The water-absorbing speeds of nylon resins at 23°C in water are compared in Figure 5. The water-absorbing speed of nanocomposite M1030DH is quite smaller than that of a regular nylon A1030JR, and thus M1030DH is more stable to water.

• Water Absorption and Dimensional Change

  The relationship between the water absorption and the dimensional change is shown in Figure 6. M1030DH resin exhibits a small dimensional change by absorbing water, much smaller than an inorganic-fillered nylon A3130. Nonocomposite nylon resins are excellent in dimensional stability.

Heat Aging Property

The heat aging properties of nylon resins are shown in Figures 7 and 8 (100°C and 120°C). M1030DH resin is superior in heat aging property to A1030JR.
